I don't think we'll see Google splitting off their gmail/gtalk logins from everything else, and I don't necessarily agree that they should. One of the major benefits to using google services is the shear amount of services you get without having to login to multiple sites, or keep multiple bookmarks, google takes care of it all for you. We're slowly seeing this same idea take over the rest of the web with facebook connect and OpenID. People want convenience and don't like remembering a ton of passwords, or even having to retype a login/password on every site they go to. Ideally, for most internet users i'm sure, FB connect or OpenID or Google would take over the "login market" and include a key fob, so you just log your computer onto the internet and you're good to go. But I agree with most here, a key fob is, well, key.
